A New Study of Blind Deconvolution with Implicit Incorporation of Nonnegativity Constraints
Figure 5
Experimental results on Images 5-6 with Blur 1. Row 1, l-r for Image 5: the PSNR/SNR is lowered from 27.48/15.36 by 0.92/0.97 to 26.56/14.39 using Algorithm 1 but increased by 5.93/6.27 to 33.41/21.63 using Algorithm 2. Row 2, l-r for Image 6: the PSNR/SNR is increased by 11.6/11.96 from 20.19/12.11 to 31.79/24.07. Our model is capable of restoring many detailed features and sharpening edges. Several of the blood vessels become visible in (d) and very fine details can be distinguished in (g).
